Abstract

In a method and a device for carrying out the method, a roller, having an ink-absorbing outer surface, is rolled over a freshly printed site of a printing product after a defined time and at a defined pressure and a quantity of ink, which is removed from the printed site by this means, is transferred to an unprinted site by rolling the roller over the latter and is then evaluated visually or densitometrically. <IMAGE>

Description

Изобретение относитс  к печатной промышленности , в частности к устройству дл  проверки на отмарывание..The invention relates to the printing industry, in particular to a device for checking for pickling.

Целью изобретени   вл етс  упрощение конструкции при одновременном облегчении обращени  с устройством.The aim of the invention is to simplify the design while facilitating handling of the device.

На фиг. 1 показан вид спереди предлагаемого устройства дл  проверки на отмарывание; на фиг. 2 - то же, вид сбоку.In FIG. 1 is a front view of an apparatus for checking for picking; in FIG. 2 - the same side view.

Предлагаемое устройство 1 дл  проверки на отмарывание согласно представленной форме выполнени  содержит установленный с возможностью вращени  ролик 2, снабженный руко ткой 3. Ролик 2 жестко посажен на вал 4, размещенный с возможностью вращени  на открытом вниз U-образном носителе 5. При этом ролик 2 выступает за концы 6, 7 U-образного носител  5. Ролик 2 состоит из дискообразной средней части 8, снабженной красковоспри- имчмвым, легко деформируемым покрытием 9. С обеих сторон средней части 8 расположены два других, трудно деформируемых диска/Ш, 11. Диски 10, 11 по сравнению с покрытием 9 могут быть охарактеризованы как жесткие и краскоотталкивающие. Радиус дисков 10, 11, составл ющий, например 17 мм, меньше, .чем радиус покрыти  9, составл ющий , например 18 мм. Руко тка 3 закреплена на верхней стороне 12 U-образного носител  5.The proposed device for checking for pickling according to the presented embodiment includes a rotatably mounted roller 2, provided with a handle 3. The roller 2 is rigidly mounted on the shaft 4, rotatably mounted on the U-shaped carrier 5. The roller 2 protrudes for the ends 6, 7 of the U-shaped carrier 5. The roller 2 consists of a disk-shaped middle part 8, equipped with a paint-sensitive, easily deformable coating 9. On both sides of the middle part 8 are two other, hard-deformed disks / Ш, 11. Disks 10, 11 compared with the coating 9 can be characterized as hard and paint-repellent. The radius of the discs 10, 11, for example 17 mm, is smaller than the radius of the coating 9, for example 18 mm. The handle 3 is fixed on the upper side 12 of the U-shaped carrier 5.

Дл  определени  характеристики по от- марыванию свежезапечатанную печатную продукцию 13 располагают на жесткой подставке 14 (например, стол). На печатной про- дукции 13 выбираетс  релевантна  печатна  область или релевантна  лини  наката , предпочтительно полна  тонова  лини . После определенного времени (например, 20с) после печатани  выбранна  лини  наката прокатываетс  роликом 2. При этом ролик 2 прижимаетс  к печатному продукту 13 до тех пор, пока покрытие 9, дефор- миру сь, не будет образовывать одну поверхность прилегани  с дисками 10, 11. При этом покрытие 9 при определенном давлении вступает в контакт с исследуемым печатным участком. После определенного срока высыхани  печатна  краска исследуемого участка более или менее снимаетс  роликом 2 и за смет продолжени  движени  качества переноситс  на незапечанный уча00To determine the curing characteristic, a freshly printed product 13 is placed on a rigid stand 14 (e.g., a table). On the printed product 13, a relevant print area or a relevant roll line, preferably a full tone line, is selected. After a certain time (for example, 20 s) after printing, the selected run-up line is rolled by the roller 2. In this case, the roller 2 is pressed against the printed product 13 until the coating 9, deforming, forms one contact surface with the disks 10, 11 In this case, the coating 9 at a certain pressure comes into contact with the investigated printing area. After a certain drying period, the printing ink of the investigated area is more or less removed by roller 2 and, due to the continuation of the quality movement, is transferred to the unprinted area

сток. Полученный таким образом отпечаток исследуетс  и оцениваетс  визуально или при помощи денситометра. Плотность краски в отпечатке предоставл ет печатнику возможность определить предрасположенность к отмарыванию использованной печатной краски по отношению к использованной печатной бумаге. Формула из об р е т е н и   1. Устройство дл  проверки на отмары- вание, содержащее смонтированные на основании контактное тело и элемент дл  передачи усили , отличающийс  тем,stock. The fingerprint thus obtained is examined and evaluated visually or with a densitometer. The density of the ink in the print allows the printer to determine a predisposition to smear used printing ink relative to used printing paper. Formula of the Inventions 1. A device for checking for cooking, comprising a contact body mounted on the base and an element for transmitting force, characterized in that 00 что контактное тело выполнено в виде ролика , состо щего из плотно прилегающих друг к другу дисков, при этом средний диск снабжен красковосприимчивым покрытием и имеет радиус, превышающий радиус боковых дисков, при этом последние выполнены из краскоотталкивающего материала.that the contact body is made in the form of a roller consisting of disks closely adjacent to each other, while the middle disk is provided with a paint-resistant coating and has a radius exceeding the radius of the side disks, the latter being made of a paint-repellent material. 2. Устройство по п. 1, отличаю щее- с   тем, что основание имеет руко тку и выполнено U-образной формы, а ролик установлен в основании с возможностью вращени .2. The device according to claim 1, characterized in that the base has a handle and is U-shaped, and the roller is rotatable in the base. 11 ЛL
